[Class 111] In apparatus for collecting sludge for reintroducing into aeration tanks in connection with sewage plant using the activated-sludge system, the sludge deposited on the floor of a settling tank is gathered by scoops or scrapers carried by a rotatable bridge and is removed by siphon pipes associated with the scrapers, the sludge being then passed into a trough from which it is drawn off by a siphon and delivered into a well provided with an outlet for returning the sludge to the aeration tanks or elsewhere. As shown, a settling tank A has an outer and an inner circular wall provided with rails a, a<2> to support'the wheels of a rotatable bridge B. The bridge is adapted to rotate about a shaft b<3> mounted in a central sludge well A<8> which is positioned within the inner circular wall A<4>. Liquid from the aeration tank passes through an inlet pipe A<6> and through an annular grille A<7> on the wall A<4> into the settling tank. The bridge B supports a number of pivotallymounted siphon pipes c each of which is secured to a V-shaped scoop or scraper d. Each pipe can be raised, for examination, by a winch. With each pipe c is a bent portion Cx dipping into a vessel e adapted to communicate with a trough f. The inner end of the trough leads to a well f<1> into which one limb of a main siphon pipe g dips. The other limb dips into an annular trough connected by outlets h<2> to the central sludge well A<8>. An outlet pipe A9 from the well A<8> leads to a chamber A <10> having a valve-controlled outlet leading to a pump for conveying away the sludge. Priming connections and valves are provided for putting the apparatus into condition for raising the sludge from the settling tank.

Title: Baffle and draft control members for vertical draw sheet glass making machines
IPC: C03B25/12
Filed: 1966-03-07
Abstract: <PICT:1083051/C1/1> A vertical draw sheet glass making machine having end walls and side walls with vertically spaced clean-out openings extending there-through includes at least one baffle plate 14 pivotally mounted to a side-wall 12 of the machine adjacent to the lower edge of a clean-out opening 10 and extending inwardly and upwardly to a point adjacent to the path of travel of the glass sheet, means for rotating the plate about its pivot in a first direction to a position where its innermost end lies adjacent to the side wall of the machine, and means for positively limiting the degree of rotation of the plate in the opposite direction.  At any one level there is a clean-out opening on each side-wall of the machine and preferably there are seven baffle plates for each clean-out opening mounted on shafts 30, the arrangement being such that the three baffle plates on either side of the machine, together with the centre baffle plate, may be pivoted by operating a handle on the corresponding side of the machine. The degree of rotation of a baffle plate away from the clean-out opening is limited by stop member 46 attached to the plate bearing against a micrometer screw 50.  The lower edge of the clean-out opening 10 has a plate 52 which overlies the shafts 30, and is so designed that when the plates 14 are positioned with their innermost end adjacent the machine side wall their outermost end overlies plate 52.  Thus any broken glass is caught by these baffles and easily removed from the machine.  The baffle 14 can also be used to control the draught in the vertical draw chamber and thus the annealing of the glass sheet.  The clean-out openings are normally closed by doors 20.

Title: Multiplexed serial register architecture for VRAM
Inventor: HILTEBEITEL NATHAN RAFAEL
IPC: G11C11/4096
Filed: 1997-06-26
Abstract: A dual-port DRAM in which a single serial latch is shared between two pairs of folded bit lines from two arrays of memory cells (10, 20). A first set of multiplexer devices (14, 24) selects one of the two pairs of folded bit lines from each of the arrays (10, 20), and a second set of multiplexer devices (16, 26) selectively couple one of the remaining folded bit line pairs to either the parallel port or the serial latch for access to the serial port. This arrangement greatly decreases the consumption of chip real estate. At the same time, it makes unlimited vertical scrolling possible through the use of a copy mode that can be carried out in two operating cycles, and facilitates masked writing, while at the same time reducing clocking complexity. <IMAGE>

Title: Process for removing heavy metals from waste waters, precipitating material for the process and process for producing precipitating material
Inventor: FUELOEP JULIUS
IPC: C01B17/42
Filed: 1989-05-24
Abstract: The invention relates to a process for separating heavy metals from waste water and to precipitant for carrying out this process and to process for manufacturing the precipitant. It known to use the alkaline hydroxide precipitation and the sulphide precipitation to separate heavy metals from waste water. However, these known processes are associated with serious disadvantages which, in the final analysis, have prevented their use in practice. The invention proposes, in a process according to the generic part, to combine the intrinsic advantages of sulphide precipitation in an acid medium, namely the extremely low residual solubilities of the heavy metals, with the considerable reduction in the risks of possible overdosage, i.e. safety from formation of hydrogen sulphide. The precipitant used is designed in such a way that the sulphide and other precipitates in the treated waste water automatically flocculate out at a pH of about 7.5, the sludge becoming separated from the clear water without addition of flocculating agents. The agent for separating heavy metals advantageously consists of alkaline earth metal polysulphides or mixtures of alkaline earth metal polysulphides with other alkaline earth metal sulphur compounds.

Inventor: PHILLIPS GARETH T
IPC: C07C233/00
Filed: 1987-07-27
Abstract: S-(-)-atenolol (4-(2-hydroxy-3-isopropylaminopropoxy)phenyl acetamide) is obtained by a process including the step of stereo-specific epoxidation by an ester of 4-allyloxyphenylacetic acid using a micro-organism capable of stereo-selective epoxidation, e.g. Pseudomonas oleovorans, to produce the corresponding ester of 4-(2,3-epoxypropoxy)phenylacetic acid which is predominantly in S configuration. Pseudomonas oleovorans ATCC 29347 produces at least about 90% of the epoxypropoxy compound in S configuration. The resulting epoxypropoxy compound can be converted into atenolol, maintaining the high proportion of S configuration, by reacting the epoxypropoxy compound with isopropylamine and converting the ester group to an amide group by reaction with ammonia.

Abstract: PURPOSE:To prevent deterioration of an image due to image trailing and unsharpening by using a combination of 2 kinds of polycarbonate resins each having molecular weight in a specified range in a specified blending ratio for a photosensitive layer. CONSTITUTION:The photosensitive layer contains at least one of the polycarbon ate resins (I) each having a number average molecular weight of <=1.5X10<4>, and at least one of the polycarbonate resins (II) each having a number average molecular weight of >=4.5X10<4> in a (I)/(II) blending ratio of, preferably, (30-95):(70-5) by weight. If (I)/(II) is below 30/70, proper abrasion resistance cannot be obtained, and if it is above 95/5, abrasion resistance and viscosity are made too low. If the number average molecular weight of the resin (II) is <4.5X10<4>, viscosity-raising effect is small, resulting in disabling control to proper abrasion resistance, thus permitting the photosensitive body superior also in durability to be obtained.
